I need help using the View command in Auctex running in emacs. This is essential for viewing pdfs and without it I can not make TeX documents. In my emacs file I have the following (which was created by M-x customize-variable):

(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
'(TeX-view-program-list (quote (("Preview" "\"open -a Preview.app %o\""))))

Now I open up a .tex document and enter C-c C-c (I have already compiled):

Emacs gives: Command: (default View)

I hit enter

Emacs gives this default command: View command: dvi2tty -q -w 132

I hit enter and emacs says: View: done. but displays nothing in a pdf reader!

dvi2tty is intended for text only devices, and the command actually creates a new buffer in emacs which attempts to display the pdf file (it is very messy). Anyway, if I replace dvi2tty -q -w 132 with `open -a Preview.app %o' (I am running Mac os X 10.8.4 and Preview is the name of the default pdf reader) then Preview opens the pdf!

How do I change the default View command from dvi2tty -q -w 132 to open -a Preview.app %o?
